PFLAG has been active for many years with an army of straight allies, families of lgbt and friends of lgbt. This is the perfect fit for straight allies to find a fit to engage in this struggle for equal rights/civil rights for all who are lgbt.
I have been a civil rights activist in Arkansas for many decades and so has my husband. We have sued the state and overturned, with the massive help of ACLU, laws that were openly bias. Our problem in AR is finding safe venues for all who believe this bias is wrong yet fear retaliation. Our primary focus are for those who do not have so easy an option to speak up or be out, lgbt youth, especially those of color. We do not get help from others and live where marriage is so far removed from the daily lives and desperate needs of our youth and adults who simply seek safe housing, food, safe schools, and life.
What of cases that were not via court but utilization of current laws that were used to extend to lgbt folks? Title lX was used in 1997 against Fayetteville, AR school district. Office For Civil Rights agreed that title lX did not define gender of harasser and or victim and therefore included lgbt students. Fayetteville school district was investigated and found in violation, a first but not last, of a gay student's title lX and 14th amendment rights. They are now being sued in federal court by a family for failing to halt the harassment toward a student who was percieved gay but is not. They are now at risk for loss of federal funding. Title lX applies to all primary, secondary and colleges who recieve federal funding.
